TY - JOUR PY - 1996// TI - Analysis of steering shimmy accompanied by sprung mass vibration on light duty truck – Fundamental mechanism JO - JSAE review A1 - Kimura, T. A1 - Hanamura, Y.

One is self-excited vibration at low vehicle speeds, and the other is forced vibration at high speeds. Shimmy on a light duty truck has been considered as that of self-excited vibration. However, it causes vibration not only on the steering system but also on the cabin, with a large amplitude at relatively high speeds. The phenomenon was analyzed by performing vehicle tests and numerical simulations using simplified models. As a result, the phenomenon was found to be self-excited vibration basically caused by two closed-loop vibration mechanisms.
